What You Need
- Semaglutide vial (common strengths: 3 mg, 5 mg)
- Bacteriostatic water (BAC water)
- Insulin syringe (0.5 mL or 1 mL)
- Alcohol prep pads
Step-by-Step Instructions
Step 1: Clean vial tops. Swab both vial stoppers with alcohol prep pads.
Step 2: Draw BAC water. For a 5 mg vial, adding 2.5 mL of BAC water creates a concentration of 2 mg/mL. Adjust based on your target dose using our BAC water calculator.
Step 3: Inject slowly. Angle the needle so the water runs down the glass wall of the vial. Do not aim directly at the powder.
Step 4: Mix gently. Roll the vial between your palms until the powder is fully dissolved. The solution should be clear.
Amounts Seen in Research
Semaglutide research references often describe amounts near 0.25 mg per week in early weeks, with gradual increases reported later. These figures are for reference only and are not a recommendation. The exact syringe units depend on the concentration you created.
Storage
Semaglutide is more stable than most reconstituted peptides. Refrigerate at 2 to 8 °C. Reconstituted semaglutide is typically stable for up to 56 days (per manufacturer data). Protect from light.
